Development of the Mk 84 Low Drag General Purpose Bomb
for use by the United States armed forces began in the 1950's.
The Mk 84 bomb, which is fitted with 30 in (0.762m) spaced
suspension lugs, is packed with 942 lb (426 kg) of Tritonal or
H-6. The known inventory of Mk 81, 82, and 84 bombs is 1.13
million.

The GBU-27 is a modified GBU-24 Paveway III designed for
internal carriage in the F-117A. This LGB carries the
designation GBU-27 /B and uses a BLU-109 /B penetrator bomb
for its warhead. The main modifications made to the GBU-24
were to have shorter adaptor rings and to use the GBU-10's rear
wing unit to decrease the bomb's length, and to clip the canards
in order to make the weapon fit into the small F-117A Bomb
Bay. The other major difference was the use of radar absorbing
materials in order to prevent the bombs from being picked up by
enemy radar once the aircraft's bomb doors were opened. As a
result of these modifications, the GBU-27 has a shorter range
than the GBU-24, which can also be launched at lower altitudes.
Guidance is by semi-active laser, the scanning detector assembly
and laser energy receiver being mounted in the front of the
canister behind the glass dome. After the bomb is released the
laser error detector measures the angle between the bomb's
velocity vector and the line between the bomb and target.
Steering corrections are made by moving the nose mounted
canard control fins to adjust the bomb's trajectory to line up with
the target. The tail fins/wings are for stabilization purposes only.
Target illumination for the system may be either by an
aircraft-mounted laser marker (not necessarily the parent
aircraft) or a ground-based laser transmitter.

A parallel program to the AGM-154 JSOW the GBU-31 JDAM
program began in the late 1980's. The goal of the program was to
produce a low cost guided munition. Interesting to note is the
GBU-31 is soon to be replaced by the GBU-32/35. This new
weapon, will utilize a I-1000 (1000lb)(452.5kg) penetrator
warhead and is intended for future use in the F-22 raptor. This
weapon, the GBU-32/35 is being used to size the raptor's bomb
bay's.
The GBU-31 utilizes both the Mk 84 and BLU-109 warheads.
Due to the Mk 84's low cost, and commonality, it was chosen for
the solid model seen above. The GBU-31 consists of three major
subassemblies. The warhead (Mk 84), Saddleback stub wing
assembly (attaches at hardpoints, three components), and a bolt
on tail cone guidance kit.
The guidance kit, contained within the replacement bolt-on tail
cone consists of the following key elements: combined inertial
measuring unit and GPS receiver; flight control computer;
battery and power distribution unit; tail actuators and four
movable clipped delta fins in a cruciform configuration. In
keeping with other GPS guided weapons, the unit is believed to
be fitted with two GPS antennas, one on top of the unit for initial
flight and one in the tail for good reception during terminal
maneuvering.
Prior to bomb release the guidance unit will be fed with aircraft
position, velocity and target coordinates through the aircraft to
bomb interface. After release the bomb will guide itself to the
target by means of rear fin deflection which are driven by
commands from an onboard computer that is constantly being
updated by the GPS. The combination of the INS/GPS is
expected to allow the bombs to hit within 10m (32.8ft) to 15m
(49.2ft) of their targets. Wind tunnel tests in 1996 are reported to
have cleared JDAM for release at up to M 1.3.

In the late 1980's the US Navy began a review of conventional
weapons with the intention of reducing the number of weapon
types. New systems were selected for future development:
JDAM, TSSAM, JASSM, and the advanced interdiction weapon
system to be later named Joint Standoff Weapon (JSOW).
The JSOW program is intended to replace six existing weapons:
the AGM-65 Maverick, AGM-123 Skipper, AGM-62A Walleye,
Rockeye and APAM (Anti-Personnel/Anti-Material)
submunition dispensers, and laser- and TV- guided bombs.
Of particular attention on the previous list is:
1) All weapons are air to ground.
2) This weapon is designed to replace the GBU-27,
one of the weapons on the RFP attachment 3 list.
The JSOW is an aerodynamically shaped, unpowered glide
dispenser with a rectangular cross-section body shape. It is made
up of three major sections: a streamlined nose fairing that houses
the guidance and control system, a rectangular center section
payload container for holding the bomblets (this is fitted with
two folding high aspect ratio wings on its upper surface, and two
standard 30 in (0.762 m) spaced suspension lugs); and the tail
section which has six fixed, sweptback rectangular fins
positioned radially on the boat tail and contains the flight control
system.

The Small Smart Bomb is a 250 lb (113 kg) weapon that has the
same penetration capabilities as a 2000lb (905 kg) BLU-109, but
with only 50 lbs (22.6 kg) of explosive. With the INS/GPS
guidance in conjunction with differential GPS (using all 12
channel receivers, instead of only 5) corrections provided by
GPS SPO Accuracy Improvement Initiative (AII) and improved
Target Location Error (TLE), it can achieve a 5-8m (16.4 to 26.3
ft) CEP. The submunition, with a smart fuze, has been
extensively tested against multi-layered targets by Wright
Laboratory under the Hard Target Ordnance Program and
Miniature Munitions Technology Program. The length to
diameter ratio and nose shape are designed to optimize
penetration for a 50lb (22.6 kg) charge. This weapon is also a
potential payload for standoff carrier vehicles such as
Tomahawk, JSOW, JASSM, Conventional ICBM, etc. The
Swing Wing Adapter Kit (SWAK) is added to give the SSB
standoff of greater than 25 nm (48.6 km) from high altitude
release. The wing kit is jettisoned at a midcourse way point if
penetration is required so that velocity can be increased after
wing release. For soft targets the wing kit continues to extend
the glide range until small arms threat altitude is reached. At this
point the wings are released. With INS/GPS guidance, coupled
with AII, a 6-8 m (19.7 to 26.3 ft) CEP can be achieved. This
wing kit allows the SSB to be directly attached to the aircraft at
any 300 lb (135.75 kg) store station. The major advantage to the
250 lb (113.125 kg) small smart bomb is an improved number of
targets per pass capability.
Weapon Information:
The Advanced Medium-Range Air to Air Missile (AMRAAM)
AIM-120 development program was started in 1975. It was
designed to follow on and better the performance of the Aim-7
Sparrow and be carried on the F-14, F-15, F-16 and F/A-18
aircraft. In the late 90's a modified(smaller) version of the
missile, the AIM-120C was developed to be fitted to the F-22
Raptor. This newer version also incorporates a dual mode active
and passive radar seeker. The AIM-120C is deigned to be rail,
ejector or trapeze launched. On the F-22 the AIM-120C is
launched using an EDO corp. LAU-142/A hydraulic / pneumatic
ejector.
In a typical engagement the missile is launched and first guided
by on-missile inertial navigation, with command guidance
updates from the launch aircraft. The missile then goes into the
mid-course autonomous mode and continues to guide by by
inertial navigation only. Finally, the terminal mode is
automatically initiated by the missile itself when the target is
within rage of the missile's active monopulse radar seeker, which
then guides the missile onto the target aircraft.
